The addition of a solar panel atop an EWP floater could result in a power plant capacity increase of between three and 10 percent

We first encountered Eco Wave Power back in 2012 when the company began testing a novel wave energy harvesting system that turned the rise and fall of coastal waters into electricity. The system went from the lab to the real world in 2016, and a second grid-connected project was announced for Jaffa Port in Israel earlier this year. Now EWP is looking to get more from its energy harvesters by adding solar.

EWP says that its latest venture came about after clients showed interest in having a number of different renewable energy sources as part of their energy mix. Solar or wind farms could be an option, but not every location has enough space available for such things. The Swedish company could have suggested putting solar panels atop the wave energy system's land-based power station, but it might not always be located outside (as is the case in Gibraltar) and there may be limited roof space available if it is.

Instead, EWP opted to try and make use of the upper surface of its floaters – which are installed on existing structures like breakwaters and piers – the idea being that energy could then be harvested from both solar and wave sources.

Potential system advantages are reported to include more electricity generation without increasing the system size, no additional costs associated with land purchase for solar installation, and less energy loss from heat as a result of a cooling effect on the panels from the surrounding water.

The company has applied for a new international patent and an Israeli patent this week, and has also started initial testing of the combined energy harvesting setup. If these limited tests prove successful, solar panels will be fitted to all of the floaters on the EWP station at Jaffa Port, ahead of possible installation at the Gibraltar site.

This is a joke right? There must be a million better places to mount a solar panel besides on a thing that is splashed with salt water.

A patent?! So, you can get a patent for every type of exposed surface that the sun hits? I need to keep this post short because I have a thousand patents to submit this afternoon.

Actually I can't think of a better place to mount a solar panel. Let me list the reasons why: 1. It's already rigged with the electric capturing system (cuts down on implementation cost). 2. It's in unobstructed sunlight. 3. Solar panels need to be cooled and are usually made waterproof because no matter where you are it rains. 4. Aesthetically doesn't make a difference on the back of a giant float. 5. Will likely get a once yearly maintenance review with the floating system, something often forgotten on rooftops. 6. When the weathers bad you get waves no sun, when the weathers good you get sun no wave, sometimes you get both (offsets down times). Not a reason but a good testimony to mention. Boaters have some of the best solar panel systems setups some have gone so far as to convert there boats to run on electricity powered by sun and generators & boaters who have solar swear by the reliability maintenance free system & they absolutely love them.

Water is the best place to put a solar panel, as the Earth's albedo and heat exchange are not changed. The water provides needed cooling for the panel.

Thanks Matt & Doug, now Tom can use your good info for his patents cutting way down on the number feasible.

How much efficiency is lost if salt dries on the panel and is not washed for an extended period?
